Lugar was once considered pretty conservative-back in the 1970s.
Reagan would be considered a RINO in today's Republican Party (not the GOP's fantasy "Reagan")
Lugar is a conservative. He just apparently isn't conservative enough.
This race has my blood boiling, and we're still over a year out. Mourdock's now attacking Lugar for co-sponsoring a bill with Obama. He must not know that happens all the time in Washington, and some of the Senate's most conservative members have done it with Senators even more liberal than Obama was.
